Gable Vents

The importance of a gable vent is to simply and naturally vent the hot air out of your attic.  Gable vents that vent properly will add years of life to your roof and home. 

The first ones used by home builders were not louvered but more decorative.  The builders would leave an opening in the gable end and then use wood slats to make a decorative cover to help keep out birds.  But the decorative vent cover was still vented.  Later, about a hundred and fifty years ago, the louvered gable vent became popular since it would also keep blowing rains out of the attic.  Around a hundred years ago, screen was added to keep out smaller critters such as wasps.  Then, metal vents were introduced to prevent rot. Wooden louvers were not designed for all the sun and rain they were forced to endure.  Galvanized vents were very common in the 1950’s.  Easy to obtain and then paint them to match the home.  But there was a major rust issue determined after they are about ten years old.  Even if they were painted regularly, the welds would deteriorate and weaken the vent louvers.  Not long ago, vinyl was introduced to solve all these vent issues.  Little did contractors know, they had a worse issue.  Vinyl does not take to heat very well, and it began to crack and warp.

Some are unaware that there are actual specs for these to work correctly and last longer.  The standard life-time warranty is 50 years with most manufacturers and most do provide products to stand up to their warranty.  But some custom gable vents are not made to any specs or standards.  These quickly become a disappointment to the customer.  That is why, even if you are ordering a custom gable vent, we will marry your design and measures with the required specs to keep your warranty intact.

These louvered gable vents are manufactured in a different manor than other manufacturers.  We do not butt cut the louvers and pop rivet them into a track.  This leaves a vulnerability.  Wind provided vibration of the gable vent and the louvers can eventually work loose.  Using a rail system locks the ends of the gable louvers onto the rail backed up by a pop rivet.  This reduces the wearing on the pop rivet from the vibration and more than quadruples the life of the gable vent.

The next step is to seat the gable vent into it’s cover or flange.  We offer all four flange types to match your installation preference.  If you need to mount the gable vent inside a brick opening, the no flange has no nail fin to have to remove.  For siding installs, we have the j channel flange.  The j channel is built into the outer most of the gable vent trim allowing the siding to slide into the track.  Dealing with stucco?  The back flange is great for mounting on the wall and applying the stucco around it.  But, the most popular flange with contractors is the front flange or nail fin.  This is the most versatile gable vent option.  The vent slides into the gable wall from the outside and can be mounted in many ways.  Also, the gable vent is already trimmed out.  Shop gable vents in the gable vent department of Onyx Xteriors to locate and order, buy custom gable vents and louver vents ready to pick up or ship.

When ordering a gable vent, ask yourself these 3 questions:

2. What grade of gable vent do I need? 
We offer the contractor grade gable vents in widths up to 24 inches.  These are good gable vents but have limitations because of their lack of stiffeners.  We also offer the best gable vents on the market as the Signature Series.  These vents have 4 fold louvers and all the bells and whistles.

3. How long do I need the gable vent to last? 
This is a tough decision since this is where choosing the right gable vent manufacturer is prudent.  Look at the way the manufacturer makes their vents and decide for yourself.  Take into consideration the fasteners they use and read their reviews.
